Project Alpha: Part Two: The Change

Tommy Crane is the first resounding success of the Facility’s top-secret project, but Kent knows that things aren’t quite cause for celebration. Tommy has become a savage beast with nothing but breeding and rutting on its mind, a creature of pure instinct and sexuality.
 
Kent needs to escape the Facility in order to find a cure for Tommy, but with things rapidly escalating, it may be too late for him to do anything but try and save himself. Even that might be easier said than done when the pheromones get to him and the beast finds him in a compromising position.

The Change is an 8,500-word short story and second in a series.
